This is definitely messy... You get an infinite canvas to type, draw, make presentation, calculate digits, add media files, links, and a lot more. You can customize the canvas to your desire, you can change the fonts as well. You can highlight words, you can also bookmark important titles or sentences. You can search for a ‘y’ note that contains ‘x’ word too. Preety much everything but you’ll have to spend more taps if you want to archive a page or a note. You’ll have to enter the page/note then tap on the 3-dots (top-right) then tap on ‘move to’ then select archive.
That's the main thing I miss on Android. I use NotesPlus and Notability on my iPad but struggled to find something similar on my Galaxy Note 4. I finally settled on FiiNote. I haven't tried it on a proper tablet, but it's very powerful and flexible. https://play.google.com/store/apps/details?id=com.fiistudio.fiinote
I used FiiNote which has so many great features.

And this stylus: https://www.amazon.com/Mixoo-Capacitive-Sensitivity-Precision-Universal/dp/B01N2OJX82
This was a quick and dirty test to help me learn the app. I am pretty pleased with it!
The touchscreen works quite well in my experience. As far as your graph drawing capabilities go, if a Windows 10 application / software can do it, this thing can since it runs standard Win10. I never needed that, so I can't be 100% sure. I do use FiiNote for it (link is for the Android version which is quite similar, I've used that as well) and think it might be able to do what you're looking for.
Because I am middle-aged and of feeble mind, I need a simple note-taking app. Fiinote is great for writing down grocery lists, to-do items or jotting something down immediately before it flits from my brain. There may be similar ones out there but I find it very easy to use.
The Android equivalent of the VoidTools' Everything application for PCs. Basically, a search/indexing tool for quickly finding anything on your phone no matter where it might be if you know part of the filename.
Might be worth looking at Fii note
FiiNote ?
If you have some kind of stylus, Fiinote is truly incredible.
I like Fii Note
I think Fiinote does this, also Fiiwrite from the same developer
I have found an app that has it built in! Any ttf font! FiiNote
Try out FiiNote I recently discovered this gem.

The menu is clunky but it does so much!
